The following table describes all of the supported Livy properties. When installing Apache Livy, you can choose the Livy Helm chart version. To set a property during the installation, use the command `--set <property>=<value>`.


| Property | Description | Default | 
| --- | --- | --- | 
| image | The Amazon EMR release URI of the Livy server. This is a required configuration. | "" | 
| sparkNamespace | Namespace to run Livy Spark sessions. For example, specify "livy". This is a required configuration. | "" | 
| nameOverride | Provide a name instead of livy. The name is set as a label for all Livy resources | "livy" | 
| fullnameOverride | Provide a name to use instead of the full names of resources. | "" | 
| ssl.enabled | Enables end-to-end SSL from Livy endpoint to Livy server. | FALSE | 
| ssl.certificateArn | If SSL is enabled, this is the ACM certificate ARN for the NLB created by the service.. | "" | 
| ssl.secretProviderClassName | If SSL is enabled, this is the secret provider class name to secure NLB for the Livy server connection with SSL. | "" | 
| ssl.keyStoreObjectName | If SSL is enabled, the object name for the keystore certificate in the secret provider class. | "" | 
| ssl.keyPasswordsObjectName | If SSL is enabled, the object name for the secret that has the keystore and key password. | "" | 
| rbac.create | If true, creates RBAC resources. | FALSE | 
| serviceAccount.create | If true, creates a Livy service account. | TRUE | 
| serviceAccount.name | The name of the service account to use for Livy. If you don't set this property and create a service account, Amazon EMR on EKS automatically generates a name using the fullname override property. | "emr-containers-sa-livy" | 
| serviceAccount.executionRoleArn | The execution role ARN of the Livy service account. | "" | 
| sparkServiceAccount.create | IF true, creates the Spark service account in .Release.Namespace | TRUE | 
| sparkServiceAccount.name | The name of the service account to use for Spark. If you don't set this property and create a Spark service account, Amazon EMR on EKS automatically generates a name with the fullnameOverride property with -spark-livy suffix. | "emr-containers-sa-spark-livy" | 
| service.name | Name of the Livy service | "emr-containers-livy" | 
| service.annotations | Livy service annotations | \$1\$1 | 
| loadbalancer.enabled | Whether to create a load balancer for the Livy service used to expose the Livy endpoint outside of the Amazon EKS cluster. | FALSE | 
| loadbalancer.internal | Whether to configure the Livy endpoint as internal to the VPC or external. Setting this property to `FALSE` exposes the endpoint to sources outside of the VPC. We recommend securing your endpoint with TLS/SSL. For more information, see [Setting up TLS and SSL encryption](https://docs.aws.amazon.com/emr/latest/EMR-on-EKS-DevelopmentGuide/job-runs-apache-livy-security.html#job-runs-apache-livy-security-tls). | FALSE | 
| imagePullSecrets | The list of imagePullSecret names to use to pull Livy image from private repositories. | [] | 
| resources | The resource requests and limits for Livy containers. | \$1\$1 | 
| nodeSelector | The nodes for which to schedule Livy pods. | \$1\$1 | 
| tolerations | A list containing the Livy pods tolerations to define. | [] | 
| affinity | The Livy pods affinity rules. | \$1\$1 | 
| persistence.enabled | If true, enables persistance for sesions directories. | FALSE | 
| persistence.subPath | The PVC subpath to mount to sessions directories. | "" | 
| persistence.existingClaim | The PVC to use instead of creating a new one. | \$1\$1 | 
| persistence.storageClass | The storage class to use. To define this parameter, use the format storageClassName: <storageClass>. Setting this parameter to "-" disables dynamic provisioning. If you set this parameter to null or don't specify anything, Amazon EMR on EKS doesn't set a storageClassName and uses the default provisioner. | "" | 
| persistence.accessMode | The PVC access mode. | ReadWriteOnce | 
| persistence.size | The PVC size. | 20Gi | 
| persistence.annotations | Additional annotations for the PVC. | \$1\$1 |

| envFrom.\$1 | Additional envs to set to Livy from a Kubernetes config map or secret. | [] | 
| livyConf.\$1 | Additional livy.conf entries to set from a mounted Kubernetes config map or secret. | \$1\$1 |
